Failure recovery processing method in intersected ring network, node and intersected ring network

Abstract

The invention discloses a fault recovery processing method in an intersecting ring network, a master node of each Ethernet ring network in the intersecting ring network is allocated with a respective priority, and the method comprises the following steps: a normal polling message with own priority is sent by the intersecting ring network after the normal polling is detected by the master node in a fault state in the intersecting ring network; if the normal polling message with priority sent by other master nodes is received by the master node in the fault state, whether the own priority is higher than the priority in the normal polling message or not is judged, if so, the normal polling message is transmitted; and the master node in the fault state judges whether the normal polling message sent by itself is received in the predetermined time length, if so, a secondary port is blocked. The invention also discloses a master node, a transmission node and the intersecting ring network. The invention can provide an effective fault recovery processing method for the arbitrary topological intersecting ring network.

Description

technical field [0001] The invention relates to the technology of the Ethernet ring network, in particular to a fault recovery processing method in the intersecting ring network, a node and the intersecting ring network. Background technique [0002] At present, the Ethernet ring network is gradually popularized and applied. figure 1 It is a schematic diagram of the structure of a single Ethernet ring network. see figure 1 , in a single Ethernet ring network, including a master node and multiple transmission nodes, the master node and each transmission node transmit business data on the Ethernet ring network to complete various business functions. [0003] Since the Ethernet ring network is a ring network structure, it is necessary to prevent loops, so as to avoid broadcast storms caused by unknown unicasts and broadcasts being circulated on the ring. At present, for a single Ethernet ring network, there are relatively mature technologies to avoid loops and ensure data tr...
